3.4.3 Machine trigger, server trigger and conditions
Function description, conditions
For triggers, a distinction is made between conditions and triggers.
• Conditions are the preconditions in order that a trigger is initiated. The
condition must be available before the trigger signal or at the latest at the
same time. If a condition is missing, then the trigger signal does not execute
the control monitor. If the condition comes after the trigger signal, then the
control monitor is not executed.
• Triggers executes the control monitor if the conditions are available at the
instant in time that the trigger is fulfilled.
For pure machine triggers, the states of the signals are the logic operation of the
trigger precisely in the cycle with the somewhat scattered query of the conditions.

Function Description Type
Name A name can be assigned to the AND'ed list of
conditions. If the field remains empty or is deleted,
the system generates a name from the
parameters. The name varies according to the
screen resolution.
If the name already exists, a consecutive number
is automatically added in parentheses.
If the name is too long, the number added can
only be seen in a tooltip.
